- Melatonin secretion. Melatonin is secreted by the pineal gland in the brain. The secretion of the hormone occurs in response to the light and dark cycles. Normally, its production is reduced by being in bright light. On the other hand, being in darkness stimulates melatonin release.This is why it is often called ‘the hormone of darkness’.elatonin is secreted by the pineal gland in the brain. The secretion of the hormone occurs in response to the light and dark cycles. Normally, its production is reduced by being in bright light.

- Society for Endocrinology. Hormones. Leptin is a hormone secreted from fat cells that helps to regulate body weight. The name leptin is derived from the Greek word ‘leptos’ meaning thin. It is sometimes referred to as the ‘Fat Controller’.

Prolactin Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation, and nursing. Prolactin is secreted in a pulsatile fashion in between these events.Prolactin also plays an essential role in metabolism, regulation of the immune system, and pancreatic development.here is a diurnal as well as an ovulatory cycle in prolactin secretion. In many mammals, there is also a seasonal change in prolactin release. During pregnancy, high circulating concentrations of estrogen and progesterone increase prolactin levels by 10- to 20-fold.

cholecystokinin cholecystokinin. a polypeptide hormone secreted in the small intestine, which stimulates gallbladder contraction and secretion of pancreatic enzymes. gastrointestinal hormone liberated from the intestinal mucosa in response to arrival of the products of digestion from the stomach. It stimulates secretion of pancreatic enzymes and gallbladder contraction. Abbreviated CCK, CCK-PZ. Called also cholecystokinin-pancreozymin, pancreozymin.

Incretin Hormone Print Text Size: A A A. A hormone that stimulates insulin secretion in response to meals. The two most important incretin hormones are called glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP).Understanding how these hormones work is helping to yield new treatments for Type 1 and Type 2 diabetes.urthermore, scientists have also observed that people with Type 2 diabetes have diminished insulin release in response to meals and have speculated that they may have defects in the release or action of their incretin hormones. GLP-1 is made in the small intestine and colon and is released in response to food.

Secretin Secretin functions as a type of fireman: it is released in response to acid in the small intestine, and stimulates the pancreas and bile ducts to release a flood of bicarbonate base, which neutralizes the acid. Secretin is also of some historical interest, as it was the first hormone to be discovered.

Resistin From Wikipedia, the free encyclopedia. Resistin also known as adipose tissue-specific secretory factor (ADSF) or C/EBP-epsilon-regulated myeloid-specific secreted cysteine-rich protein (XCP1) is a cysteine-rich adipose-derived peptide hormone that in humans is encoded by the RETN gene.esistin has been shown to cause high levels of 'bad' cholesterol (low-density lipoprotein or LDL), increasing the risk of heart disease [...] resistin increases the production of LDL in human liver cells and also degrades LDL receptors in the liver.

Leptin Resistance: An Obstacle to Weight Loss What Leptin Is. Leptin is a hormone secreted by adipose tissue (fat cells) that tells you you’re full. (Its opposite hormone is called ghrelin, which tells you you’re hungry. You can remember this because the word ghrelin sounds like a stomach growling.) Because leptin is secreted by fat cells, you produce more leptin as your weight increases.

Incretins There are two main incretin hormones in humans, GIP (glucose-dependent insulinotropic peptide; also known as gastric inhibitory peptide) and GLP-1 (glucagon-like peptide-1). Both hormones are secreted by endocrine cells that are located in the epithelium of the small intestine.ncretin hormone release is regulated in a similar way to other digestive tract hormones. An increase in the concentration of a substance in the lumen of the digestive tract (in this case glucose) acts as the trigger for hormone secretion. The mechanism of incretin action is schematized in the figure below.
